Dan is right ! When you can get them these paraffin coated produce shipping boxes are very easily re-cycled into fire starters , or as an additional layer of dampproofing
between the ground cloth and the bottom of your tent. /////// See Link Below :

Note that the boxes are very dark and even look oil stained !
Be aware that many middle men produce shippers that deliver to the back door of Your
local super market have paid a premium price for these boxes and will expect
the Grocery to save intact boxes for recycling /reuse- boxes with some damage are USUALLY fair game !
For the Crafts ! Big AL
